T0 cZZ whom it may concern.'

Be it known that I, JACOB A. ULMAN, a citizen of the United States,residing at Baltimore city, State of Maryland, have invented certain newand useful Improvements in Non-Refillable Bottles, fully described andrepresented in the following specification and the accompanyingdrawings, forming a part of the same.

This invention relates to improvements in non-reiillable bottles; itbeing the object of the present invention to provide a bottle of thisclass in which will be overcome a certain difficulty in pouring whichdevelops undercertain conditions with certain liquids; this particulardifficulty being the liability of the valve, notwithstanding the tiltingof the bottle to pouring position, to remain seated and thus prevent thepouring of the contents of the bottle. `.bis a full understanding of theimprovenients of the present invention can best be had from a detaileddescription of an organization embodying the same, such description willnow be given in connection withV the accompanying drawings, in which-Figure 1 is a. vertical elevation of a bottle equipped with the presentinvention. Fig. Q is a vertical section of the same. Fig. 3 is a viewsimilar to Fig. 2, with the bottle tilted to pouring position. Figs. 1,5, G and T are sections on the lines 4L, 5, 6, 7 respectively, of Fig.2; and Fig. 8 is a side elevation of part of the bottle neck.

The bottle here-illustrated is that shown and described in theapplication of Maurice Switzer and Joseph D. Lacroix, filed November 7,1910, Serial No. 591,054 except for the additionthereto of one featureconstituting the present invention and which will be hereinafter fullydescribed. The following brief general description of the other featuresof the bottle will, therefore, be sufiicient.

Referring to said drawings, a represents the bottle body, terminating atits upper end in a neck portion b, to which is permanently secured bycement and otherwise a neck containing the valve and valve-controllingmechanism by which the bottle is rendered non-reiillable. The neck is,in the process of manufacture, made up of two parts c fl of porcelain,which, however, are so united by an outer film e of enamel and theinterlocking engagement of their abutting and correspondingly shoulderededges as to become, in effect, a unit or integral, as described in saidapplication of Switzer and Lacroix. The part c contains a valve seat f,of porcelain, chamfered at its lower outer edge to lit a correspondinglyshaped shoulder provided by the inner upper edge of the neck portion Z)of the bottle body c, and at its upper edge fitting into a recess g inthe lower end of part 0,' a hollow inverted cupshaped valve it,preferably of porcelain, resting on this valve seat; an approximatelypear-shaped valve-seating weight i, of glass or porcelain, restingsidewise on the upper end of the valve Zz.; and a baffle y' which, amongother things, limits the movement of weight integral vertical ribs f:being also formed in the neck part c for guiding valve ZL in itsvertical or opening and closing movements. Batlle j, which is integralwith the neck part eZ, closes the bottle neck except for a passagebetween it and the inner surface of the latter, into which, however,project two horizontal rows of alternating or staggered projections Z,m, which will permit the passage of the liquid contents of the bottlebut will prevent the insertion of a wire or the like sufliciently farinto the bottle neck to tamper with the valve Zt or weight z'. At theends of each projection Z m are vertical ribs a, which it is obviouswill engage the end of any wire or the like inserted in the bottle neckand prevent further downward movement thereof. The insertion of a wireor the like is still further guarded against by the provision ofshoulders 0 in the neckportion o projecting inwardly beneath theprojections Z, m, so that a wire cannot be passed between the outer endsof said projections and the inner surface of the neck into the lower endof part o containing the valve ZL. Baflie j is also provided at itslower end with a. recess p for the accommodation of weight z', thisrecess and the weight .2', valve 71 and seat f being of such size and soarranged relatively to each other as to provide for free rockingmovement of said weight, and also a limited movement thereof, and ofvalve ZL longitudinally of the bottle neck.

lVhile the bottle is in an erect position, the valve 7L and weight z'will occupy the positions in which they are shown in Fig. 2, with thevalve 7L held to its seat by its own weight and that of weight z'.W'hen, however, the bottle is tilted to pour out some of its contents,and passes from a horizontal portion to the partially inverted positionshown in Fig. 3, the valve, relieved of the weight of weight z', whichhas moved into recess 7), and aided by the pressure of the liquid in thebottle, will be unseated and assume the position in which it is shown inFig. 4f. On

turning the bottle upwardly, as soon as it.

passes a horizontal position, and approaches an erect position, weightz', rocking in recess p and moving downwardly at right angles to thebottle neck, will, as the liquid recedesV from the bottle neck, forcevalve L to its.

seat, aided, of course, by the weight of the valve itself.

The bottle neck, made in two parts c, d, united as described in saidapplication of` Switzer and Lacroix, is secured to the bottle j 'body aby a collar r of suitable metal inclos- 1 ing the upper end of the neckportion Z) ofl the bottle body and the lower portion of the neck memberc, both of which portions are provided with circumferential indentationsor recesses, into which the metal of collar r is forced or spun by asuitable tool. To prevent leakage, a gasket s, of suitable material isinterposed between the abutting edges of vthe neck portion o and neckmember c. At

'the base of the recess p in baflle plate or plug 'y' are providedprojections t which prevent adhesion of the weight z' to the bottom ofthe The valve mechanism of the bottle oper-` this vacuum, and,therefore, the adhesion of the valve to its seat, may be avoided by acontracted air passage u through which in the closed position of thevalve the bottle neck above the valve seat communicates with the body ofthe bottle. Such air passage is, in the particular valve mechanism shownand described herein, preferably formed in the upper end of the valve7L, because it has been found that in this position it is less liable topermit the passage of liquid downward through it than it might be inother positions, particularly as the weight z' in its closed positionrests immediately on and partially closes it. By contracted air passage,as that phrase is here used, I mean a passage large enough to permit thepassage of air from'one side of the valve or valve seat to the other,but small enough to prevent, on account of the air pressure inside thebottle, the passage of any substantial amount of liquid from the neck ofthe bottle into the body thereof.

What is claimed is '1. In a non-rellable bottle the combination of avalve and seat therefor interposed between the bottle body and neck, aweight resting upon andhaving a curved surface in contact with the upperend of said valve, and a contracted air passage through said valve inline with said weight and arranged to be closed thereby, said passageconnecting tion of an inverted cup-shaped valve and seat thereforinterposed between the bottle body and neck, a pear-shaped weightresting on the upper end of said valve, and a contracted air passagethrough said valve in line with said weightY and arranged to be closedthereby, said passage connecting the body and neck in the closedposition of the valve.

4:. The combination, inthe neck of Va bottle, of a valve-seat having acentral opening in line with the neck-opening, an inverted cup-shapedvalve normally resting at Vits lower edge on said seat and closing theopening therein and adapted toA tilt upon and thenfmove bodily away fromsaid seat when the bottle is tilted to pouring position, said valvehaving a contracted air passage, a weight normally resting upon theupper end of the valve and controlling its movements, said weight beingin line with the ai'r passagev and having a curved surface in contactwith the valve, and means above the weight for limiting the movementsthereof, substantially as' described.

In testimony whereof, I have hereunto set my hand, inthe presence of twosubscribing witnesses.
